-// -------------------------------------------------------------- Specification
-//
-
-//
-// The EG2Timer is a fast-access low latency deadline-based timer designed
-// for high-performance timekeeping operations. It consists of one counter
-// counter and three match registers against that counter. Each match register
-// consists of a 32-bit value that is compared on each clock cycle to the
-// current count value. If the values match and the match register is enabled
-// for generating an interrupt, an edge triggered interrupt will be fired. The
-// register can also be configured with an "interval" value such that the
-// match register is automatically moved forward by the given interval to
-// generate periodic interrupts. The main counter is 32 bits and runs at 15MHz.
-// The register layout of the timer block appears below.
-//
-// Offset Register Size
-// 0x00 GlobalControl 4
-// 0x04 CounterValue 4
-// 0x08 Timer0_Match 4
-// 0x0C Timer0_Interval 4
-// 0x10 Timer0_Control 4
-// 0x14 Timer1_Match 4
-// 0x18 Timer1_Interval 4
-// 0x1C Timer1_Control 4
-// 0x20 Timer2_Match 4
-// 0x24 Timer2_Interval 4
-// 0x28 Timer2_Control 4
-//
-// Register Descriptions:
-//
-// GlobalControl - Controls global state relating to the timer block. On reset,
-// this register's value is 0. This register is Read/Write.
-//
-// Bit Function
-// 31-1 Reserved. Read as 0, always write 0 to maintain future
-// compatibility.
-//
-// 0 Enabled. When set to 1, the main counter is enabled and will
-// count. When set to 0, the main counter is disabled and will
-// not run.
-//
-// CounterValue - A Read/Write register containing the current value of the
-// counter. Writes to this register must be done with caution as they do
-// not alter or adjust the contents of the match registers. On reset, the
-// value of this register is 0.
-//
-// TimerN_Match - A Read/Write register that contains the match value that this
-// interrupt is primed against. When the global counter equals the match
-// value, an interrupt will be generated. If the interrupt is set for
-// periodic mode, the Interval value will be automatically added to the
-// match value when the interrupt occurs. On reset, the value of this
-// register is 0.
-//
-// TimerN_Interval - A Read/Write register that contains the periodic interval
-// to add to the match register if the interrupt is armed for periodic
-// mode. On reset, the value of this register is 0.
-//
-// TimerN_Control - A Read/Write register containing a bitfield that controls
-// the behavior of the match register and associated interrupt. On reset,
-// the value of this register is 0.
-//
-// Bit Function
-// 31-2 Reserved. Read as 0, always write 0 to maintain future
-// compatibility.
-//
-// 1 Periodic. When set to 1, the value in the Interval register will
-// automatically be added to the value in the Match register and
-// written back to the Match register when a match occurs. When
-// set to 0, the Match register will not change when a match
-// occurs.
-//
-// 0 InterruptEnable. When set to 1, an interrupt will be generated
-// when a match occurs. When set to 0, no interrupt will be
-// generated when a match occurs. The periodic bit is still live
-// however, the Match register will continue to get accumulated
-// with the Interval register on matches.

-Routine Description:
-
- This routine is responsible for initializing the timer hardware. This is
- guaranteed to be the first timer routine called by the HAL. It must prepare
- the timer for use by beginning the timer's counter ticking if the counter
- is readable, setting the intial input clock divisor to 1 if applicable,
- and masking all interrupts. If the timer's stop routine is called, this
- routine will be called before the timer is queried or armed again. It will
- not be called between every rearming of the timer.
-
- This routine will not be called concurrently with any other calls to
- this HAL Timer extension. For per-processor timers, this routine will be
- called once on each processor. A failure on any processor blocks the timer's
- use on all processors.
-
-Arguments:
-
- TimerData - Supplies a pointer to the timer's private context. The contents
- of this pointer were specified when the timer was initially registered,
- and may be modified inside this routine. The HAL does not interpret any
- data deferenced from this pointer.
-
-Return Value:
-
- Returns an NT status code indicating success or failure. If a successful
- status code is returned then the HAL may subsequently call further routines
- in this HAL extension to query or arm the timer. If a failure code is
- returned, this HAL extension will not attempt to use this timer unless the
- Initialize routine is called again and succeeds.

-
-/*++
-
-Routine Description:
-
- This routine arms a timer to fire an interrupt after the given number of
- timer ticks. For timers that only interrupt on rollovers, this simply
- enables the interrupt, the tick count parameter is ignored. If the timer
- is currently armed for a different mode or tick count, this call is
- expected to replace that programming. This routine will not get called
- concurrently with other timer calls, except on per-processor timers, where
- it may get called concurrently on different processors.
-
-Arguments:
-
- TimerData - Supplies a pointer to the timer's private context, whose
- initial content was supplied when the timer was registered.
-
- Mode - Supplies the mode to arm the timer in, which will be one of the
- modes the HAL extension advertised support for when registering the
- timer. The modes are as follows:
-
- OneShot - Arms the timer to fire the given number of ticks from now.
- Only one interrupt is expected to come in. The HAL does not make
- assumptions on whether or not the expiration of this interrupt
- causes the counter to stop. The Query Counter routine will not be
- called while a timer is armed to fire an interrupt.
-
- Periodic - Arms the timer to fire periodically with an interval of the
- given number of ticks. The first interrupt should happen
- approximately the given number of ticks from when the arm timer
- function was invoked.
-
- PseudoPeriodic - Arms the timer with the same functional behavior as
- periodic mode, with the knowledge that the timer will have to rearm
- itself during the acknowledge interrupt routine. This mode is
- expected to have slightly worse performance than pure periodic mode,
- but is expected to generate periodic interrupts at the exact rate
- specified.
-
- TickCount - Supplies the number of ticks from now that the timer should
- assert its interrupt in. For timers that are only capable of
- interrupting on rollovers from their maximum value to 0, this parameter
- is ignored.
-
-Return Value:
-
- Returns and NTSTATUS code indicating success or failure. If the timer
- returns success, then the interrupt is expected to come in the specified
- number of ticks from when the function was called, with a tolerance of
- however long the function took to execute. If the routine fails, then no
- timer routines will be called again until the timer Initialize routine is
- called again and succeeds. In most cases, returning a failure code results
- in a system bugcheck.
